4 Claims.'

'Ihe invention relates to counting and printing devices for recording the number and identification of agreeing data present on a plurality of records.

A divisional application Serial No. 593,740, filed February 18, 1932, is concerned with certain printing devices revealed herein.

An object of the invention is to provide means for comparing the perforations in a plurality of 1g record or cross-index cards. l

Another object is to provide devices for counting the number of times agreeing perforated index points appear on the records. The separate counts arehy accumulated and a printed record is made of the total.

l A-feature of the invention is the printing of a list of numbers identifying certain perforated points on record cards, and a printed numeral indicating the number of index points recorded.

A further object is to perform the entire comparing and reccrding'operation automatically, the plurality of data cards being inserted in .the ma chine and the starting circuit closed, the machine senses each column on all the cards at every index point in the columns concurrently. The sensing operation having been started, con= tinues uninterruptedly until an agreement of indicia or perforations in the cards indicates the necessity for recording at what point in the sensing operation lthe agreement is had. The machine pauses in the sensing operation while this fact is recorded .and counted, then the sens-a ingis againautomatically resumed.I When the cards have been completely sensed, .the total of number of times agreement was hadv is recorded and the machine stops and remains stopped until it is started by manual means.

Although it is apparent that the invention is adapted for use in many accounting and statistical 4g systems, it is illustrated in the present disclosure in connection with an example concerning the use of a statistical system for the study of the occurrence of complications in disease. In other words, having a certain disease present in a case,

45 what is the probability of one or more other l diseases being present in the same case.

To gather the facts from a large number of cases a set of disease cards, one for each disease,

is perforated in accordance with the routine 50 records concerning each case. The perforation of f the cards is carried on `in a punching machine separate from the devices of the present invention.

-Ten disease record cards may be perforated, each having one hundred columns of index points with 55 ten index points in a column thus providing'space (ci. css-e111 for the perforation registration of one thousand cases. A

Reading the disease card from left to right, the columns ci index points are numbered to 99 inclusive. 'I'he vertical or row positions in each column are numbered the same as the usual Hollerith card, i. e., 0 at the top of the column and 9 at the bottom; The horizontal rowsof `index points on the card `are designed to represent hundreds identification. From the above it may be gathered that if a. hole is punched atI 0 in the thirty-sixth column, it represents 35 and may be so recorded. If, however, a hole is punched in the thirty-sixth column in the fth index point position, it will represent 535 and may be so recorded. It will thus be apparent that one thousand numbers may be represented each by a hole perforated in the cross index card.

When a certain casel is complicated with two or more diseases, the related disease cards are perforated in the same index point position. After the data relating to all the cases has been trans erred to the set of cross index cards, any coinblnation of such cards can be compared to des termine the number and identification of the cases having the complications studied. Thecomlparing and recording of the cases meeting the re= quirements set could be accomplished by hand but it would be a long and'tedious operation. This comparing and recording operation is performed quickly and accurately by the devices of the present invention. A printed record is produced upon which is indicated the total number of cases in Whichthe combination of diseases studied occurred; and a list of numbers identitying the cases. c

in the preferred form disclosed, the comparing and recording device consists of a plurality of re ceivers each adapted to receive oneindex card and each receiver being equipped with a card sensing device. These plurality of card receiving devices are connected to a tabulating machine type of mechanism. The tabulator is equipped with one or more adding counters and a printing mechanism adapted to print a plurality of numerals, said printing mechanism being under control of the cross-index card being sensed through an intermediate set of differential timing contactors. more index cards may be inserted for comparison at any one time. The sensing devices consist oi a plurality of sets of brushes connected in an electric circuit, one set engaging the surface ofl each record card. The brushesare connected in series. In the sensing operationthe cards move In the use of the device, two or the brushes.

No. 391,874, Illed September 11, 1929, corresponding to British Patent No. 362,529. The cards are .stepped along column by column by means of an' escapement and the brushes detect by the closing of the circuit the presence of corresponding holes in all of the. cards sensed. By means of a comlnutator connection only one brush of a set is eilective during a sensing operation, the sensing of the top row of the card being effective first and the brushes sensing the other rows being made effective lh succession from the top to the bottom n brush in the set. The entire card is sensed from left to right. After the sensing of 'the top or zero horizontal row of index points on the card, the card returns so that the brushes are again at the lelt hand end of the card and are madeeffective to sense the horizontal row marked 1,-, that is the index points representing 100 to 199. Again the cards are moved and sensed from left to right, this operation continuing until the ten horizontal rows have been detected,

If at any point in the movement of the card over the brushes a corresponding hole in each card is detected, a circuit is closed through all of This, through the instrumentality of a relay, causes the sensing operation to be suspended and another circuit to be closed to cause 'the tabulator to go through an adding and recording cycle. Intermediate contact devices that are positioned along with the cards determine the value of the particular hole sensed and in turn energize emitters moving in synchronism with the tabulator printing devices, thus causing the tabulator to' record the identification of the perforation sensed by printing of a record sheet.

In the printing cycle the tabulator also adds a unit to an adding counter each time such agreement is reached. This counter accumulates all the units resulting from such agreement and car. ries a total representing the number of agreeing cases. y

The electric circuits are so arranged that the completion of the adding and printing cycle on the part of the tabulator releases the relay above mentioned and causes the re-initiation of card comparing. This operation continues until the last position on the cards is sensed. At that point, a total from the counter is automatically taken and printed on the same sheet with thelist of identification numbers and the counter is either reset or not in accordance with the wishes of the operator. A

In the ordinary-use of the machine the index cards may then be .withdrawn and another set inserted for comparison, the new set being either wholly new or comprising possibly one or more records already compared. Thus the comparison of data on an unlimited number of cross index record cards is made possible.

A set of drawings accompany the specication and form part of the disclosure.

Fig. 9 is a detail view in side elevation taken as indicated by line 9-8 in Fig. 5, and showing the construction of the commutator disks and brush holders which are advanced step by step by thel card return mechanism.

'I'he machine, as shown in Fig. 3, is provided with three card receivers. 'I'he number of card receivers may be increased to compare a larger number of cards in combination, by merely adding other card frames 2l.. As these card receivers are alike in structure, a description of one applies to the .others as well. The card frames 2| are mounted on a common base 22. When a card 23 is inserted in a frame it rests on a shoulder 24 (Fig. 4) with its left end leading under the sensing roller 25 (Fig. 6). -Both ends of the card 23 are engaged by extension brackets 26 iixed to thecard shifting escapement rack 21. From the side of the rack 21 there protrude two studs 28 which arevheldin a slot 29 in the frame, thus guiding the sliding movement of the rack. A spring drum 30 in engagement with rack teeth 3l on the bottom of rack 21 (Fig. 5) tends at all times to urge the rack to the left. A separate rack and escapement mechanism is provided for each dlierent positions, each position presenting one column of index points on the card for sensing. The escapement mechanism is controlled by a magnet 35 (Fig. 6) mounted within the card frame 2|. The armature-36 of the magnet is secured to a shaft 31 which projects out of the card frame (Fig. 5) and has secured to its end. an arm 38. A spring 38 norinally tends to hold the armature 36 away from the magnet 35. The arm 38 is connected by a link 4|! to a crank 4l xed on a shaft 42 to which is attached a two armed lever 43. The lever is rocked in a counterclockwise directlon when magnet 35 is energized; and when so rocked, a pin 44 on one arm oi' the leverlifts pawl 33 while a pin 45 on the other arm of the lever lowers the pawl 32 into engagement with the teeth 34 on rack21, so that pawl. 33 when lowered by the return movement of associated magnet 35 are mounted adjacent. the

tact blades is fixed' an insulation block 48 which is in the path of the end of an arm 49 fixed to shaft 31. When magnet 35 is energized arm 48 is rocked and acts to open contacts 41, thus breaking the circuit through the magnet 35, deenergizing it and allowing shaft 31 to return to normal position, whereupon contacts 41 are again closed to'energize the magnet.

Thus the magnet 35 is alternately energized g and deenergized, causing the escapement mechanism to function to pei'mit column by column shifting of the record card. This continues until coinciding perforations are, sensed in the record cards; then devices, to be described hereinafter in connection with the wiring diagram, act to break the circuit through all the magnets for a moment while the index number of theperforation is recorded; after which the card shifting operation is again resumed.

The record card perforation sensing devices are shown in Fig. 6. There it is noted that electrical connections to the-movable sensing brushes t are established by contact between the mounting blocks 5| of the brushes and stationary spring contact plates 52.v The series of contact plates 52'are carried by a block of insulating material 53 xed to the card frame.

Each spring 52 is adapted for continuous sliding electrical contact with the associated brush holder or block 5| which carries itsparticular analyzing brush 50. The series of brushes 50, of which there are eleven, are adapted to bear against a metal cylinder or roller 25 mounted on a non-conducting roller 54 which is carried by a shaft 55. The brushes 5% are carried by an insulating brush holder 5E secured between a pair of side plates 51 of a yoke or bail shaped member designated generally by reference numeral 58. Each side plate 51 of the yoke shaped frame 58 is suspended or supported at its upper end by a link 59 pivoted to the frame portion and at its lower end the plates 51 are supported by means of a parallel link 6|. Intermediate each plate 51 and related link Si is a toggle plate linkage member 62 which is pivoted upon a spring stud 63 securely fastened to the frame member 2 l.

The end of lthe link 6| distant from its connecting peint to the toggle plate 62 is pivtally secured to an armature structure 6d, the latter being pivoted'v at 65 to the frame member ed. The armature structure til is attracted against the tension of a spring b when-magnet 61 is energized, at which time the counterclockwise rocking movement of each toggle plate 62 about its pivotal point 53 will be effective to elevate the frame 56 resulting in the contact of the individual analyzing brushes 5t? with the contact roll 25.

The brush holder 5 and analyzing brushes d@ extend completely across the card frame, and when a card 23 is in the frame it will pass between the roller 25 and all of the brushes 5@ except the top one, as shown in Fig. 7, which brush is in continuous contact with the contact roller 25.

Associated with each card table is a resilient plate 68, Fig. 6; adapted to be held down by a latch 69 during normal operation. When the latch is released and the plate 68 elevated a card may be placed upon the card carriage. Attached to the plate 68 is a. contact operating member 10 adapted to engage and close contacts 1| when the plate is latched. Upon elevation of the latter Dto place a card on the carriage table,

contacts 1| will open and since they are in series connection with the magnet l1 (see Fig. 7) the latter will be deenergized to cause a shifting of the brush holder B1 to its lowermost position to permit the card to be shifted on top of the card carriage without danger of damaging or bendl ing the brushes 50.

A means is provided for automatically returning the card carriage racks 21 with the cards 23 to their normal starting position by power instead of by manual' operation. Such an arrangement expedites operationof the machine and requires less attention on the part of the operator. 'I'he mechanical parts for obtaining this result will now be described followed by a description of the electrical controlling instrumentaiities.

Secured to the underside of the base 22 of the machine is a motor 12 (Fig. 5) having a clutch connection to a stub shaft 13 to which is secured a worm wheel 14 (Fig. 4) in'mesh with a worm gear 15 secured to a vshaft 10 one end of which has secured thereto a ratchet shaped clutch element 11 (see Fig. 5). Loosely mounted on shaft 16 is a gear 18 lmeshing with a gear 19 secured to shaft 80. Also fixed to the shaft are three single tooth clutch bushings 8| in engagement with pawls 82 mounted on the sides of gears 83 which mesh with the teeth 3| on the underside of racks 11. Clockwise rotation of gear 19 serves to move racks 21 to the right back to the initial card sensing position. A disk v84 secured to the side of gear 18 acts as a driving connection between the clutch 11 and the gear.

Pivted at 8E to disk 86 is an arm 8B havingfa.y clutch tooth 'l. The free end of arm` `88 is connected to a toggle plate 58 by a link 88, the end of toggle plate t8 distant from its pivot 90 being articulated at Si to a rod 92. 'The rod is urged into position by a spring 98 and fits in an aperf' ture in a pin 93 rotatably mounted on the disk 81|.` By virtue of this constructionrod 92 and plate 08' act as a toggle, spring 96 acting to impositively hold tooth 01 in or out of engagement with the clutch teeth of ratchet wheel 11.

' For'the purpose of effecting the clutching action a magnet 95 is provided and when energlzed attracts an armature 96 pivoted at $1, so that an arm t@ engaging a pin 99 of arm 86 will rock the arm and place the tooth 81 in engagement with ratchet Wheel 11. Through link 8s the toggle connection will be moved centrifugally with spring at acting to hold clutch tooth in engagement with the ratchet teeth. Gear 18 will thereupon be driven in a counterclockwise` direotionY substantially a single revolution, shifting rack 21 to the right just as if it was caused by movement of a nger piece. This action will result in moving the card carriages so that the cards are brought opposite .the initial sensing position.

At the termination` ofthe counterclockwise movement of gear 18, a tail |00 of plate 86 will strike a projection |0| of a fixed plate |02 to edect the disengagement of the tooth 81 and ratchet wheel 11 by a reverse action., The operation of the toggle back over dead center will cause the tooth s] to be retained out of engagement-with the teeth of the ratchet wheel 11 Plate 84 is preferably lmounted on gear 18 by pin and slot connections |03 (Fig. 5) and connected to each other for driving movement by springs |04. This construction is provided to 'take up the shocks dueto starting from a position of rest andthe sudden stopping of the rotaan arm |05 (Fig. 6) the free end of which is adapted to bear upon an insulating block |06 to open contacts |01 when magnet 95 is energized. Contacts |01 are retained opened by a latching bell crank |08 a lug |09 of which is yadapted to be struck at the termination of the driving movement of the gear 18 by a bent up plate ||0 (Fig. 5) secured to the latter. Contacts |01 as indicated in Fig. 7c are interposed in the circuit of brush magnets 61 so as to cause the lowering of brushes 50 during the powerrestoration of thecard carriages: the circuit is closed at the termination thereof to provide for the contact of the brushesV 50 with roller '25. Below contacts |01 are motor control contacts III which are latched closed upon an energization of magnet l95 to complete the circuit through motor 12 (see Fig. 7) and are unlatched in the manner just described, to stop the motor at the termination of the driving operation.

' When. the card carriages move from the last column sensing positionv to the end of the escapement movement, t o sets of contacts are operated; one set of contacts is closed to complete the circuit through the card return devices, and the other set is opened to disable card sensing and carriage escapement. For this purpose a projection ||2 extending from the lower edge of rack 21 is adapted to cam an insulating pin I I3 standing in its path. The pin overlies the upper contact blade of contacts ||4 and the lower blade of contacts I.I5; the pin thus serving,

when lowered, to close contacts ||4 and open contacts II5. lThe functions of these contacts are more fully discussed hereinafter in an explanationof the wiring diagram.

The devices about. to be described, serve to render the brushes 50 eiective singly and in succession, the brush for the 0 row rst, next the 1 row brush, etc. The commutator connections for selecting the brushes are shown in Fig. 7c. There it is noted that each brush 50 is wh'ed to a separate contact segment IIB on the commutator |I1 and each set of brushes is wired to a separate commutator section I| 8, the wires leading from. the brushes being attached to the ass ociated segments which are arranged in order yabout the section II8. A pivoted contact frame |I9 (Fig. 9) in the commutator carries a pair of brushes that close the circuit between a common contact ring |20 and each of the segments. The brushes of the three sets are wired in series by connection wires |2 (Fig. 7) and |22 be-v tween each ring |20 and the eleventh brush 50 contacting with contact roller 25. The frame I9 is adapted to be swung step by step about its pivot so that a circuit is established through the contact roller 25, any one of the brushes 50 in the 0 to 9 row, the corresponding segment |I5,l

brushes in frame II9, then through ring |20 and back to the lin'e. I, The object of this ferm of construction is to provide means for sensing only one row of index points on the cards at a time, and also to sense the rows in succession, starting with the 0 index'row. The devices for moving the frames |I9 are actuated after the last index point in a row is sensed. The card return mechanism already described serves` to actuate the card sensing brush selection shift in a manner about to be described.

Attached to the armature 96, Fig. 5, at the pivot 91 is an arm |23 carrying a feed pawl |24. ,The

pawl is urged by a spring into cooperation with aratchet wheel |28. The shaft |21 (Fig. 9)' uponl which the ratchet |26 isiixed also carries four u frames II9, three of which cooperate with com-A mutators I|1 shown in Fig. 7, andthe other cov.)perates with a similar commutator I 28 showjnn Fig. ,'Ib; the purpose of commutator |28 will be explained further on vin the specification'. Turning again to Figs. 5 and '7 it is noted that at the beginning of a card comparing operation the frames I|9 stand in a position to close the card sensing circuit through the 0" row .analyzing brushes 50. 'I'he frames II9 remain in this position during the movement of the cards until the last column of index points on the right side of the cards pass the brushes 50. Then, as already explained, magnet 95 is energized to operate the clutch and bring the cards back with the first co1- uinn of index points to the left under the brushes. 'I'he movement of armature 96 carries alongarm |23, and pawl |24 rotates ratchet |26 through one step of movement, placing frames I I9 with the contact closed between the 1" segments and contact rings |20. Thesecond row of index points on the cards is next compared as the' cards are shifted under the brushes 50. The successive selection of brushes between the card sensing operations continues until the 9 brush or last row sensing circuit is selected, then the circuit through magnet 95 is broken by a disk |29 carried on shaft |21 and provided with an insulating segment |30 engaged by brushes I3| in circuit with the magnet. Thus, by reason of the break in the circuit, the card return mechanism is not operated after the sensing of the last rowof index points on the cards. When a new card sensing operation is desired, after the insertion of a new set of cards in the receivers, the start key |32 (Fig. 7c) may be operated to close the circuit around brushes |3| and through magnet 9,5, the armature of which vcloses contacts I|| energizing motor 12 to effect a card return movement bringing the new set of cards into the initial sensing position.

The card shifting, sensing and return devices having been described above it is thought advisable at this point in the specification to give a general outline of the operation of the tabulating or printing mechanism before describing the connections between the card handling devices'and the tabuiator.

The tabulating mechanism shown in Fig. 1, an fully described in U. 's. Patent No. 1,762,145 is adapted to be driven by the TM motor (Fig. 7*) which motor has connections for rotating a listing shaft |34 (Fig. 1) to which is attached a cam |35 for moving an arm |35 attached to the type bar lifting frame |31. 'I'he type bars |38 are lifted with a uniform motion, the notches |39 cut on the inner side of the type bars moving in succession past a latching pawl |40 which is adapted to stop the type bar in any one of its ten printing positions. Each` ofv the pawls |40 cooperates with a latch `|4| to which is attached a call wire |42 secured at the other end to an armature |43 which is swung when an associated printing magnet |44 is energized. Operation of latch I4| releases pawl |40 which then engages a notch |39. After the typebars I 38 are stopped in their printing posivto range from to 999. Another set of type bars is provided for p ting a record of the number of times coinci -perforations appeared on the cross index cards. 'Ihese type bars are adapted to print totals under control of the' accumulator for counting the items. A sample of a printed record sheet I" is shown in Fig. 8.

The connections between the card sensing mechanism and the tabulating devices comprise. a set of three emitting devices |49 such as shown in Fig. 2 and a numeral bar contact set up device |52 such as that shown in Figs.`5 and 7b. The brush holding arm |50 on the device shown in Fig. 2 is adapted to be rotated by its connection with shaft |34 in synchronism with the movement oi the type bars |38, the frame being shown with a contact made between the ,9 stud 5| which is the first one-sensed as the frame rotates. The brush on arm |50 is adapted to successively engage the studs in the contact ring as tne related type bar |38 passes the various printing positions. If a circuit is completed through one of the studs |5| the associated printing magnet IM is energized at the proper time to hold 4the type bar in printing position. The electrical connections between the tabulator controlled contact device' |49 and the numeral contact device |52 under control of the record card carriages is shown in Fig. 7b. The mechanical construction of the numeral bar device |52,`is shown in Fig. 5, while the wiring of the device is shown in Fig. 7b. In Fig. 5 it is noted that an insulating block |53 is secured to one of the racks 21 on the carriage controlling the movement of cross-index cards. Secured to the top of the insulated block |53 is a conducting contact strip |54 reaching across three rows of inserted metal contacts |55, |56 and |51, mounted on an insulation bar |58. Three extending iingers on the contact strip wipe over the contacts. The bar |58v is rigidly held to the stationary frame of the card shifting devices by a pair of brackets |59. `vThe top contact |55 is a. continuous strip reaching across the bar |58 horizontallyi' The second row of contacts |56 include ninetynine separate contact members, arranged nine' in a group with a slight space between the groups.

The third bottom row of contacts |51 are ten in number and are arranged with spaces between each other just as the groups of individual contacts in the row above. Each of the ngers on the conducting strip |55 contacts one of the rows of contacts, so that the two lower rows of contacts maintain an electrical connection with the plain rectangular contact l55. When the cards are brought into the rst column analyzing position the three lingers on the conducting strip are brought slightly to the right of the contacts on the insulating bar |55. In this position no contact is made to energize the circuits through the brush holding arms l5@ in any one of the emitting positions. If coinciding holes appear in the three cross-index cards'at this initial position, a circuit through brushes 5@ is energized and the sensing operation is suspended while a printing impression is made of the zero which is presented by the type on the type -bar lifted to the highest position. l

The escapement of the racks 2l to bring the second'colurnn on the cards over the analyzingy brushes 59, serves through the connections noted to bring `the fingers on the conducting strip |545 in position to establish a connection between the common conducting contact i55 and the first contact |56. As shown in Fig. 7b this serves t0 connect a circuit from one side of the line to a units order emitter stud |5| which is touched by a numeral is printed indicating the position of'I coinciding perforations. In the manner described thel conducting strip is drawn horizontally from one numeral -setup contact to another as the cards are analyzed column by column. The wiring connections from the nine contacts |56 in each group to thel related studs |5| in the emitter are plainly shown in Fig. 7b.

It is noted from the. construction shown in Fig. 7b that when the .tenth column on the card is analyzed. thev middle finger of the conducting strip |54 rests on an insulated portion |60 of the bar |58 between the two upper groups of contacts |56, and at the same time the left contact finger engages the contact |51 which is connected with the 1" stud in the tens order emitter. The circuits are then conditioned to control the printing of 10. r In this way the 100 vertical columns on the record cards are analyzed, each `analysis being made simultaneous with the setup of a numeral by contacts made along the bar |58. If coin-- ciding perforations are analyzed, the sensing devices are disabled Awhile printing takes place.

The wiring of the nine contacts |51 to the related brush frames M9 are shifted from the rst to the second row'analyzing positions the brushlframe |19 associated with the commutator |28 is moved to establish contact between the main line and the stud'|5| in the "1 position on the hundreds order emitter |69 in the tabulator. By means of "this connection, all numerals printed by reason oi sensing coinciding perforations in the second row ofv index points will be accompanied by a in order tol indicate thisv number li in the hundreds position on the printed sheet. After the analysis of the second row of index points the brush holder ||9 cooperating with the commutator |28 is moved to establish a circuit to the stud l5! representing 2 on the emitter.

In the above described manner the conducting strip |54 is drawn across the bar |58 ten timesL to direct numeral printing impulses through the units and tens emitters M9 while the brush holder ||9 is stepped around the commutator |28 to properly direct the printing impulses through the hundreds order emitter |69 during the analysis of one set of record cards.

At the top oi the view in Fig. '1xa is wiring diagram of the tabulating machine. Most of the connections shown are standard construction, and are fully described in Patent No. 1,762,145, iss ed .lune 10, 1930 to G. F. Daly et al. The tabula r operating controls, the printing mechanism, and the connections for resetting the accumuiators and taking a total print therefrom are explained in the patent. For the purposes of the present description it is only necessary to point out that closing the switch PS will close a circuit to the power source through lines |6| and |62; depression of the tabulator start key shown the i |88 initiates an operation ofthe tabulator motor TM; and Adepression of reset key |64 serves to operatethe reset motor RM for taking atotaling operation. 4Devices are provided for automatically initiatingoperation of the tabulator and reset motors under control of the card comparing devices. 'I'hese devices for closing shunt circuits about the control key contacts will 'be described vherein after consideration of the cardcomparing controls.

The wiring of the card comparing controls is shown in Fig. 7. -Starting at a point in the operation with card carriage rack 21 in the extreme left hand position (Fig. 5) the projection ||2 on the rack contacts the insulated pin l |3 to open contacts ||6 and close contacts H4. In this position of the card carriage, the three newcards `position with the rst column of perforations last row of perforations in the cards previously compared, disk |29 was `turned in position to bring the insulated section under the brushes |3|. The

disk remained in this position while the cards to' be sensed were placed in the receivers. Therefore, in order to complete the circuit, the comparison start key |32 is depressed and the contacts |88 closed. l

When magnet is energized, not only is the clutch connection made, but the brush holding frames ||9 are stepped around in position to sense the "0 row on the' cards, the disk |29 is advanced to complete the circuit through magnet 95 when the start key |32 is released. and contacts |01 (Fig. 6) are opened while contacts are closed. The closing' of contacts completes a circuit through the card shift motor 12. The circuit.is from line |6|, through wire |61, motor .12, wire |68, contacts and wire |69 to line |62.

'Ihe opening of contacts |01 breaks the circuit through brush magnets 61 during the card return movement. The brush'magnet circuit includes, contacts ||5 that are closed except when the card shift frame is in its last escaped position, contacts 1| normally closed, wire |10, magnets 61 arranged in multiple, wire|1|, contacts |01 and wire |69 to line |62. When the cards are properly positioned to the right, contacts |01 and are reversed by the tripping of latch |08 (Fig. 6) thus the card return motor is deenergized and the brush magnets areenergized to bring the brushes 50 into sensing position.

The cards are drawn across the sensing brushes 50, column by column, until coinciding perforations are sensed on all the records, then the escapement mechanism is disabled until a tabulating and counting operation is effected after which the card movement is resumed. The electric circuit for controlling the escapement magnets 35 is' conducted from the left side of the line |6|,

through contacts H5, contacts 1|, tabulator con- 'I'he circuit.

trolled contacts |12 normallyclosed. wire |13. three sets of escapement magnets 35 and circuit breaking contacts 41, each magnet and associated contacts being wired in series, the sets being arranged in multiple in circuit with wire |14, armature |15, contact point |16 and wire |11 to line |62. ns before explained, magnets 35 are alternately energized and deenergized by the automatic actuation of contacts 41. The escapement circuit is maintained until a card comparing circuit is made through magnet |18, then armature |15 is swung clear of point |16 break-1A ing the card shifting circuit until magnet |18 is deenerglzed at the end of the recording operation. 1

The three record cards are compared at each index point position and when perforations are presented at the same point on all, an electric cir'- cuit is made through sensing brushes 50. The circuit runs from line |6| through contacts IIS, 1|, and |12, wire |19, extra brush 50 always in contact with roller 25, to contact roller 25. Here the connections may be interrupted by the record card separating all sensing brushes 50 from roller 25, or a perforation in the card may permit contact between the two,4 only one brush 50 is effective at a time, the selection being brought about by the positioning of frame ||9 as explained in connection with Fig. 5. 'I'he circuit traced above continues from contact roller 25, through brush 50 to the segment ||6, through the brushes on frame ||9. to the\common ring |20, then to the next card analyzing apparatus through a wire |2| attached to the common contact ring '|20 and extra brush 50 on the second roller 25. From the second card sensing apparatus the series connection continues to the third card sensing apparatus by wire |22, then through the'thid card sensing means, wire |80, magnet |18, wire |8|, tabulator controlled contacts |82 and wire |83to line |62. Appearance of coinciding perforations at the sensed indexment mechanism during tabulating. Shifting of armature |84 establishes a holding circuit through magnet |18; the circuit includes line |6|, wire |86, tabulator controlled contacts |81, wire |88, contact point |89, armature |84, magn et |18, Wire |8|, contacts |82, and wire |83 to line 62. The movement of the other armature |85, closes a shunt circuit including wires |90, |9| and contact point |92,` about the start key contacts '|93 (FigJP) in the tabulator.

, As the tabulator operates, the card comparing and escapement circuits are controlled by the opening and closing of the contactsl |12, |82 and |81. Contacts |12 are opened early in the tabulating cycle tol break the circuits through the sensing brushes 50 and escapement magnets 35. Shortly after that the contacts |81 are opened momentarily, breaking the circuit around the tabulator start key contacts |93. Late in the tabulating operation contacts |82 are opened momentarily as contacts |12 are closed, thus the escapement magnets 35 may act to bring another set of index-points over the brushes 50 for sensing, before the previously sensed coinciding perforations can again act to` initiate a tabulating operation.

When the tabulator is operated, the three numeral printing type bars |38 (Flg. 1) are raised vin synchronism with the rotation of the three 2,1aac45 shown in Figs. and 7b, and through the emitters |49, impulses are sent through the magnets |44 at the proper times to stop the type bars in position to print a number corresponding to .the coinciding index points found perforated. The wiring through the printing magnets |44 terminates at one end as shown in Fig. '1a. There a connection is made from line |6| by wire |04 to the common contact brush |95, thence through contact roller |96, individual brushes |91, and printing magnets |44 wired to plug sockets |90, |09, 'and 200. In the highest order printing line a wire reaches fromf plug socket 200 to socket 203 in Fig. 7b, a wire 204 connects socket 203 to contact arm |50; the circuit continues through any of the contact studs |5| on the emitter to a contact segment ||8 on ring ||8, then through brush I|9 to the common contact .ring |20, wire 205 and wire 206 to the line |52. Thus the setting of the brush frame ||9 determines the numeral printed in the hundreds order.

The commutator unit |28 is similar inconstruction to the three brush selecting commutator units ||1 shown in Fig. 7, and it isoperated in a similar way by the'pawl |24 (Fig. 5). However, the brush holder ||9 in the hundreds bank of the printer control, is out of contact with the segments ||6 on ring H8 at the beginning of a card sensing operation. It remains in this position during the comparing of the iirst row of index points on the records. Then, when three frames I9 in the commutatore ||1 are moved to sense the second row, the brush frame in commutator |28 mounted on the shaft |21 (Fig. 5) is shifted to make contact with the 1" segment ||6 in readiness to print the hundreds order numeral in any of the numbers from 100 to 199. As the other rows on Nthe cards are selected the brush frame ||9 is moved in position to direct an impulse through the hundreds order printing magnet |44 at the proper time.

The circuitl through the tens order printing magnet |44 continues along a plug wire between plug socket |99 (Fig. 7B) and socket 202 (Fig. 7b) wire 201 to brush |50, any of the studs |5|,.wire 208, contact |51, conducting member |54, contact bar |55 and wire 20S to line |62. The numeral to be printed is determined by whichever one of the contacts |51 is contacted by member |56 during a tabulating operation, and the position of the member in turn coincides with the position of a perforation along a row on the record card,7 since the card and member |5fi aremoved together. The first ten index point positions in a row on the cards sensed do not have a corresponding active contact |51. But as the card continues to move, from the sensing of the eleventh to the twentieth index point, conductor` |54 contacts the 10 contact |51 (Fig. 7b). 1n a similar way the other contacts are successively engaged as the cards are shifted along.

The circuit through the units order printing magnet |154 is closed by a plug wire from plug socket |98 (Fig. 7B) to socket 20| in Fig. v'111, wire 209, brush |50; any of the studs |51, one of the wires 2H), a contact section |55, conductor |563, contact bar |55 and wire'ZB to line m2. The contacts |58 are arranged in groups of nine, each group containing nine sections each of which is connected by wire to one of said studs @5| in the units emitter. Nine out of every ten index point positions in a row on the card are represented by contacts |56. Between thev groups of contacts there are insulated spaces |60 upon which the conductor |54 stands when one oi the "0 index points along a row is being sensed. 'Ihus between the contacts and spaces all the index points are accounted for and represented on the third emitter.

The devices for counting the number of times that coinciding perforations appear on the-record cards, comprise `a connection in the tabulating wiring to the well-known form of electric accumulating mechanism shown at the bottom of Fig. '7a. y One form of this mechanism is illus-VK trated in Patent No. 1,307,740 to C. D. Lake@ Each time the tabulator is operated,l a'unit is added to the lowest order of the accumulator. The wiring connections reach from plug socket 2|| to which counter magnet 2|2 is wired,

in time to add a unit to the lowest order accumulator wheel. The regular form of carrying` device transfers the count above nine to the higher order accumulator wheels.

The present invention includes a means for printing a total record of the number counted on the accumulator, and resetting the accumulator if desired. This operation is performed by actuation of reset motor RM, Fig. 7B, in the usual way. Contact arms 2|8 are moved in synchronisrn with the rising counter typebars |30, the stopping of the typebrs being determined by the energization of magnets 2|9 when contact is made between the contact arms 2 I8 and the snail cams 220 mounted on the accumulator wheels. The total printing operation is controlled so that it occurs after al complete comparison of all the index points on the record cards. The total and reset controlcircuit isshown at the lower end 'of Fig. '1b. The circuit includes a pair of brushes 22| normally resting on an insulation ring 222 on a disc 223. This disc is fastened to the shaft |21 (Fig. 9) and is rotated one step upon change of rows during the comparing operation, just as disc |29 is rotated. When theninth or last row is conditioned for comparison a conducting segment 224 on disc 223 is brought around in position to close the circuit through brushes 22|. The circuit is not entirely closed, however, until the space between twocontact spots 225 and 226 is bridged. These spots are located at the end of the rst and second row of contacts, on the insulated bar |58, see Fig. 5. When the conducting member |54 passes from the ninety ninth or last comparing position, it contacts the two spots 225, 22d and closes the reset control circuit. The circuit runs from line 45|, wire 221, spot 225, conductor |56, spot 22E, wire 229 through brushes 22| and segment 222, relay contacts 229, wire 422, relay magnet 230 (Fig. 7e) and wire 423 to the other side of the line |2. When magnet 230 is energized, associated contacts 23|, Fig. 7, are operated to close a shunt circuit across the reset key contacts 232. The reset motor RM then operates the usual total printing and resetting mechanism, shown in detail in Patent No. 1,762,145 mentioned hereinbefore.

During the resetting operation relay magnet 233 is energized. Its associated contacts 229, Fig. 7b, are then opened to break the reset control circuit. The contacts are held apart by a latch 234 cooperating with contact leaf spring 235, thus limiting the resetting operation to one cycle.

When the comparing start key |32 is depressed.

that the number printed remain on the counter as a running or sub-total, the selective reset mechanism shown in the patent to C. D. Lake et ai., 1'1'15,132,sept. 9, A193mm); be employed.
